Charlton left Roots Hall with a Boxing Day defeat reflecting a slump in form and lack of urgency in play and failing to deal with set pieces, all of these issues will need to be addressed immediately as the Add1cks exit the top six and play-off places.

Charlton's sole goal was scored by Ben Reeves on 66 minutes. Southend's goals came from Simon Cox and Michael Turner on 2, 79 and 11 minutes.
